For changing the USB OTG node status from "okay" to "disabled" more space is needed, so call fdt_increase_size() to avoid the following error:
U-Boot 2023.07-rc5-0.0.0-devel+git.580eb31199be (Jun 27 2023 - 13:39:58 +0000) CPU: Freescale i.MX7S rev1.2 800 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 30C Reset cause: POR DRAM: initcall sequence 8786eafc failed at call 8781b351 (err=-3) ### ERROR ### Please RESET the board ###Ideally, fdt_status_disabled() should call fdt_increase_size() internally, so that there would be no need for manually calling it in board code.
Do it manually for now to fix the regression.
Based on the code from board/CZ.NIC/turris_omnia/turris_omnia.c.

Thanks for the patch!
